I've been trying now for a week straight to script a very specific and involved spell. I'm new to scripting in general and very new to papyrus. I've read a dozen tutorials and they all seem to be written for more advanced programmers. Can someone show me a script that lets you when you hit someone, force them into a paired animation?-Normal animations I can do fine, but paired animations are a nightmare. I also have FNIS and SKSE installed, hoping that it will make things a little easier. Paired animations can't be done with just the vanilla CK. FNIS provides infrastructure to trigger paired animations but I can't figure it out. I want to make a spell that when cast on someone it forces them into an animation (if they have it). In this case it's going to be a decapitation spell. I'd appreciate any help that can be provided in this quest.
